My neighbor shaves 15-20 times a day...
No, he's not crazy... he's just a barber.
Thomas DrummondDied 15 Apr 1840 at age 42 (born 10 Oct 1797).Scottish civil engineer who invented the Drummond light (similar to limelight illumination in theatres). As a Royal Engineer he worked on the ordnance survey and attended chemistry lectures by Faraday at the Royal Institution. In the autumn of 1825, while mapping Ireland, Drummond applied limelight to enable surveying by night as well as day and designed an improved Heliostat. To produce a bright light, using an oxygenated alcohol flame, he heated a small ball of lime to incandescent in front of a reflector. From 1828, he attempted to adapt the Drummond light for use in lighthouses, but it was expensive to operate, and by 1831, he instead turned to politics, and by 1835 was Under Secretary of Ireland. His early death was caused by overwork.« |
